Abstract: With almost every industry move towards digitization, networking, and intelligentization, the strategic significance of basic software is constantly enhanced. In the construction industry, BIM software is a key support to realize smart construction. However, at present, the core technology of domestic BIM modeling software is restrained by other countries. To promote the development of the domestic BIM modeling software, this study identified 28 domestic influence factors of BIM modeling software development from policy environment, market environment, R&D management, and core technology dimensions. Then, it carried out a questionnaire survey to collect the impact degree of these factors and applied the principal component analysis (PCA) to identify the key factors affecting the development of domestic BIM modeling software. Finally, this study interpreted the key factors through multiple rounds of in-depth interviews with industry experts and suggested the development directions for the domestic BIM modeling software.
